it might be the soil your using, i suggest when you transplant use foxfarm ocean forest. ive been using this for years and it makes everything very easy, all you have to do is give your plants some ph corrected water and thats all the soil does the rest. i have never seen such healthy growth using any other soil. they just go off man. when you do start feeding (around thirty days after the transplant) feed lightly give them half of the recommended amount. watch the growth if they look like they could use more then slowly increase the dosage until your plants are growing how you want them its always better to start off small and build up instead of burning and trying to revive a stressed out plant. Good Luck!
